Yini i-butterfly valve nezimpawu zayo?

I-Butterfly Valve, eyaziwa nangokuthi i-Flap Valve, iyi-valve eqondisa ngesakhiwo esilula. Ama-butterfly ama-valves angasetshenziselwa ukulawulwa kwemidiya yepayipi eliphansi. I-Velfly Valve isebenzisa i-disc noma i-butterfly Plate njenge-disc, ejikeleza ezungeze i-valve shaft ukuvula nokuvala.

Ama-butterfly ama-valves angasetshenziswa ukulawula ukuhamba kwezinhlobo ezahlukahlukene zoketshezi ezifana nomoya, amanzi, umusi, imithombo yezindaba ehlukahlukene, udaka, uwoyela, amafutha, imidiya ewuketshezi kanye nemidiya enemisebe. Idlala indima ikakhulukazi yokusika nokudonsa epayipini. Ingxenye yokuvula nokuvala kwe-valve yevemvane iyipuleti enomugqa onomumo we-disc ejikeleza ezungeze i-eksisi yayo emzimbeni we-valve ukufeza inhloso yokuvula nokuvala noma ukulungiswa.

Izici eziphambili zeVitterfly Valve yilezi: i-torque encane yokusebenza, isikhala esincane sokufaka nesisindo esikhanyayo. Ukuthatha i-DN1000 njengesibonelo, i-valveveveveve valve imayelana ne-2 t, ngenkathi i-value valve imayelana ne-3.5 t, futhi i-valvevely valve kulula ukuyihlanganisa namadivayisi ahlukahlukene okushayela, futhi inokuqina okuhle. Ububi be-valve ye-butterfly ebekwe uphawu lerabha ukuthi lapho isetshenziselwa ukushaya ngamandla, i-cavitation izokwenzeka ngenxa yokusetshenziswa okungafanele, okuzodala ukuncipha kanye nokulimala kwesihlalo senjoloba, ukuthi ungakukhetha kanjani kahle kuncike kwizidingo zezimo zokusebenza. Ubudlelwano phakathi kokuvulwa kwe-valve butterfly kanye nezinga lokugeleza kusisekelo kushintsha ngokuqondile. Uma kusetshenziselwa ukulawula ukuhamba, izici zayo zokugeleza nazo zihlobene kakhulu nokulimala kwepayipi. Isibonelo, uma amapayipi amabili efakwe ububanzi be-valve kanye nefomu elifanayo, kepha ukuncipha kwamapayipi kuhlukile, izinga lokugeleza kwama-valves lizohluka kakhulu. Uma i-valve isesimweni sokuthambisa okukhulu, i-cavitation ithambekele ngemuva ngemuva kwepuleti ye-valve, engalimaza i-valve. Ngokuvamile, isetshenziswa ngaphandle kwe-15 °. Lapho i-butterfly valve isekuvuleni okuphakathi, ukwakheka kokuvula okwakhiwa ngumzimba we-valve kanye nokuphela kwangaphambili kweplate butterfly kugxile emgodini we-valve, futhi izinhlangothi zombili zikha izindawo ezahlukene. Ukuphela kwangaphambili kwepuleti levemvane ngakolunye uhlangothi kuhamba eceleni kwamanzi agelezayo, futhi ngakolunye uhlangothi kuqhubekela phambili nokuqondiswa kwamanzi okugeleza. Ngakho-ke, uhlangothi olulodwa lomzimba we-valve kanye ne-valve Plate yakha ukuvulwa okumiswe ngokobunje, futhi ngakolunye uhlangothi kufana nokuvulwa okubunjiwe. I-flow velocity ohlangothini lwe-nozzle ishesha kakhulu kunalokho ohlangothini lwe-throttle, futhi ingcindezi engemihle izokhiqizwa ngaphansi kwe-valve ohlangothini lwama-throttle, imvamisa luzovela uphawu lwenjoloba. I-torque yokusebenza ye-vetterfly valve iyahlukahluka ngokuvulwa nokuvulwa nokuvala ukuqondisa kwe-valve. Kuma-valves avundlile, ikakhulukazi ama-valves amakhulu abubanzi, ngenxa yokujula kwamanzi, i-torque ekhiqizwe umehluko phakathi kwamakhanda aphezulu nangaphansi we-valve shaft ayinakwa. Ngaphezu kwalokho, lapho i-elbow ifakiwe ohlangothini lwe-valve, kwakhiwa ukuhamba kwe-bias kwakhiwa kanti i-torque izokwanda. Lapho i-valve isekuvuleni okuphakathi, indlela yokusebenza idinga ukuzivalela ngenxa yesenzo se-torque yamanzi.

I-Butterfly valve uhlobo lwe-valve olusebenzisa uhlobo lwe-disc ukuvula nokuvala izingxenye zokubuyela emuva naphambili cishe nge-90 ° ukuvula, vala noma ulungise ukuhamba okuphakathi. I-Butterfly valve ayigcini nje ngesakhiwo esilula, isisindo esincane, isisindo esikhanyayo, ukusetshenziswa okuphansi okubonakalayo, usayizi omncane wokufaka, i-torque encane yokushayela, futhi futhi inomsebenzi omuhle wokulawula ukugeleza kanye nokuvalwa kwezimpawu zokuvalwa kanye nokuvalwa kwezimpawu ngasikhathi sinye. Enye yezinhlobo zama-valve ashesha kakhulu. Ama-butterfly valves asetshenziswa kabanzi. Izinhlobonhlobo kanye nobungako bokusetshenziswa kwazo kusanda, futhi kuthuthuka kumazinga okushisa aphezulu, ingcindezi ephezulu, ububanzi obukhulu, ukubekwa obala okuphezulu, izici ezinde, kanye nemisebenzi eminingi ye-valve. Ukwethembeka kwalo nezinye izinkomba zokusebenza kufinyelele ezingeni eliphakeme.

I-Velfly valve imvamisa ingaphansi kwama-90 ° kusuka kuvuleke ngokuphelele ukuze ivalwe ngokuphelele. I-butterfly valve ne-butterfly rod ayinawo amandla okuzikhiya. Ukuze ubeke ipuleti levemvane, ukuncipha kwegiya le-worm kufanele kufakwe kwinduku ye-valve. Ukusetshenziswa kwe-Worm Gear Redicer akuvumelanga kuphela ipuleti levemvane ukuze libe nekhono lokuzikhiya, lenza ipuleti levemvane liyeke kunoma yisiphi isikhundla, kodwa futhi lithuthukisa ukusebenza kwe-valve. Izici ze-Valve Velcy ekhethekile yezimboni: Ukumelana okuphezulu kokushisa, ububanzi bokucindezela obukhulu, ububanzi obukhulu be-valve, umzimba we-valve wenziwe ngensimbi ye-carbon, futhi indandatho yokubopha ye-valve yenziwe ngendandatho yensimbi esikhundleni sendandatho yenjoloba esikhundleni sendandatho yenjoloba esikhundleni sendandatho yenjoloba esikhundleni sendandatho yenjoloba. Ama-butterfly ama-butterfly amakhulu aphezulu akhiqizwa ngamapuleti ensimbi e-welding futhi asetshenziselwa ikakhulukazi ama-ducts egesi e-flue kanye namapayipi egesi yemidiya ephezulu yokushisa.
